Longmont, Colorado — A complex custody battle escalated into a tragic incident that left one man dead, sparking a murder investigation that revealed deep-seated tensions among those involved. According to authorities, Jason Schaefer, a U.S. Postal Service employee, was fatally shot, with evidence indicating a calculated attack linked to ongoing disputes with his ex-partner, Devan Schreiner.
Jessica Price, a USPS supervisor, informed investigators that tensions ran high between Schaefer and Schreiner, particularly as their custody dispute over their five-year-old son intensified. She claimed Schaefer may have served court papers regarding the custody arrangement just hours before the shooting occurred.
Vickie Stevens, the Postmaster in Longmont, corroborated Price’s observations, stating that Schreiner, who previously worked at the Longmont post office, had exhibited unusual behavior. Stevens recounted her interactions with Schreiner, noting, “She did work with us for a brief moment. I thought she was a little bit strange.”
This volatile situation escalated further when Schreiner’s relationship with Schaefer’s younger sister, Rosa Shore, came to light. Shore indicated that her sister’s boyfriend, A.J. Ritchie, had made threats to Schaefer. Shore expressed her belief that both Schreiner and Ritchie were involved in the circumstances surrounding Schaefer’s death.
“She is just extremely angry that I have what she wants, which is a family,” Shore said, reflecting on the hostility between the two women. She recounted previous threats Schreiner made against Schaefer, warning him that Ritchie was aware of his address and armed.
In the wake of Schaefer’s murder, investigators brought Schreiner in for questioning. Detectives expressed their suspicions, suggesting the incident resembled a targeted assassination, noting the methodical nature of the shooting. “They didn’t steal anything from him. This wasn’t a road rage case. Somebody shot him because they were really upset with him,” a detective stated.
Evidence soon linked both Schreiner and Ritchie to the crime scene. Authorities arrested Schreiner on a charge of first-degree murder. Ritchie, when interviewed, admitted Schreiner had previously spoken about her intentions to harm Schaefer. Investigators also scrutinized social media communications that indicated Ritchie was aware of Schreiner’s threats and had even confronted Schaefer on the day of the shooting.
Despite warning Schaefer, Ritchie claimed he did not contact the authorities, believing that Schreiner would not act on her threats. As the investigation unfolded, Ritchie found himself facing charges of complicity in Schaefer’s murder, highlighting the intricate web of relationships and animosities involved.
In 2023, both Schreiner and Ritchie were ultimately convicted of first-degree murder and are now serving life sentences without the possibility of parole. Meanwhile, Schaefer’s mother has been granted custody of her grandson, bringing a glimmer of stability amidst the chaos that has enveloped this family.
